Your new APS power supply may be used with or without a battery. However, when combined with a high quality battery, APS power supplies can supply transient surges up to 1000 amps. In display applications where use of a battery are not possible, installation of a 1 Farad or 1/2 Farad capacitor is recommended.

APS power supplies may also be connected in parallel for even higher current operation! Because all APS Power Supplies utilize an advanced switching design, there is no low frequency transformer hum.
